In the active mode, everything happens in the following order: To do this, a temporary port is created on the client with a number in the range from 1024 to 65535 for establishing a control connection, as well as a port for data transfer. First, a control connection is established. That is, in active mode, the server connects to the client for data transfer, and in passive mode, the client connects to the server.Д«oth in the active and in the passive mode, the connection starts with sending a request by the client to the server. In a passive mode of operation, the data connection, as well as the control connection to the server, is initiated only by the client. With the active mode of operation, the client makes a control connection to the server, but the server itself makes the connection for data transfer. The ports to which data is transmitted also differ. The main difference between the active and passive modes of the FTP protocol is which of the client-server bundles makes the connection for data transfer, that is, roughly speaking, who is connected to whom. Such a connection works through a standard FTP port installed by default or in other words the default FTP port. That is so that the server receives commands from the client because this connection is called the control. Whereas the first is necessary so that the server and client can communicate with each other. The activity and passivity of the client appear only in the second type of connection. The fact is that in the FTP protocol there are two types of connection: Let's consider these modes in more detail. In the active mode, the server itself establishes a data transfer connection to the client, in passive, vice versa. Depending on the method of establishing a connection for data transfer, active and passive FTP operation modes are distinguished.

The fact is that there are two options for the development of a client-server interaction scenario. What is an active and passive mode? How are they associated with ports That is, to open the server, the client must go to the FTP server port, and through it go to the host. And in order to connect to this channel, you need a specific port. And this protocol works through the TCP channel. There is no better way to exchange voluminous data than through the FTP protocol.

Such a protocol is convenient for those people who do not care about the web-interface of the store, but who appreciate the download speed and the number of files that can be stored on the server. FTP is the data transfer protocol, necessary for the customer and server to quickly exchange various files. After all, there are more than six thousand ports, which is enough for any computer. Therefore, for each application, a unique port must be allocated - that is, a number that is not yet occupied by other programs.Дevelopers of operating systems have long been using this method of distributing programs according to numbered protocols, and it has proven itself well. If all programs run on the same вЂњtrackвЂќ, then a traffic jam will quickly form on it. A port is just a digit of the transport protocol. This is done so that applications do not conflict with each other during an attempt to connect to the network. They are needed so that programs can connect to them through the network. The computer operating system has a certain limited number of ports. If you sort everything out, then everything is extremely simple.

You will learn which is a standard port for FTP, how to change the default settings for the ports and unlock it in the firewall and router. This is what will be discussed in the article. But for this, you need to sort it well out, and in particular, you need to understand what is FTP port, what is it for and how to configure FTP port number. Through such servers, you can download music, movies, pictures, and other files, as well as handle a site with a host working through a data transfer protocol. If you try to figure it out from the very beginning, then working with the FTP server over some time will become one pleasure for you.
